Aftab, Abdullah and Rebaz Kamal were also charged with possession of weapons.

Ijaz was additionally charged with perverting the course of justice.

Shabana Bibi faces 2 counts of assisting an offender.

Detective Inspector Caroline Corfield, who is leading the investigation, said: “Clearly this is a significant development in the case but this is still very much a live investigation into Ibrahim’s murder. We are determined to get justice for Ibrahim’s family.

“We know we have not traced everyone who was at the scene that night and I would ask anyone who was there to get in touch. Last month we released images of people who were there and if anyone recognises someone from those CCTV stills I’d urge them to make contact.

“These are people who could hold valuable information. I hope those people can find it in their hearts to come forward now to help us seek justice for Ibrahim’s family.”

Another man, aged 24, failed to answer police bail and is actively being sought by officers.
